今天在 IONIC 4 Beta 发布后，我将 IONIC CLI 更新到 4.0.1。在我尝试使用

为我的 IONIC v1 项目之一提供服务之后

ionic serve command it was showing below error and warnings to me

ionic serve

如警告中所建议 [INFO] 看起来 @ionic/v1-toolkit 没有安装在这个项目中。

I tried to install @ionic/V1-toolkit using below command and i was able to use ionic serve for my IONIC V1 project from IONIC V4.0.1 CLI.

npm install @ionic/v1-toolkit -g
